52-year-old construction worker Niu Bayi is reborn back to 1984, returning to age 22 when he was seriously ill and forced by his stepmother to live in a pigsty. After rebirth, he activates a portable space. Once his body recovers, he fights back against his stepmother and stepbrother, and sets up a severance agreement. His first love He Zhenzhen helps him go out to sea, and using the seawater of his portable space, he makes three thousand yuan overnight. Niu Bayi goes out to sea and returns fully loaded one after another, but his stepbrother colludes with sea pirates to rob and blow up the ship. After sinking into the sea, Niu Bayi unexpectedly obtains golden sea willow, meets a benefactor to sell it at a high price, catches a yellow croaker with money, and buys a new fishing boat at a low price. From a loser scorned by everyone to a ten-thousand-yuan household, Niu Bayi kicks off a heaven-defying and fate-changing legend of the fishing village.
